Reactive extrusion preparation and characterization of canola meal composites reinforced by a novel polymeric chain extender

To increase the usage value of canola meal (CM), a by-product of canola oil extraction, poly (styrene-co-maleic anhydride-co-glycidyl methacrylate) (PSMG) was prepared and used as a novel chain extender to modify CM. FTIR tests showed that cross-linking took place in the CM matrix and PSMG was covalent bonded with canola proteins; furthermore, the surface of fibers present in the CM composite was covered by proteins, attributed to the …
